# Indie404 > Check whether a site returns a real 404 for a missing page instead of a soft 404, redirect, or server error. See whether missing pages return a real not-found response. Indie404 is a free web utility for one completed job for indie makers at indie404.com. One obvious entry point leads to the result. Optional controls deepen the same job. Simple checks usually answer in about ten seconds. Provider-backed checks and multi-page scans can take longer. Every answer names its source next to it. No account, no card, no premium plan, no upgrade nag, no hidden paywall. Private lookup activity is never published. Analytics is currently off, so the site sends no visit or job data to a tracker. Every page is static HTML, and each link below is that page as Markdown or plain text.
